Title: Defect detecting circuit of rectifier circuit
Inventor: TAKAHASHI YOSHIMASA
IPC: G01R31/00
Filed: 1983-04-11
Abstract: PURPOSE:To enable to detect a defect in early response and accurately by providing a current transformer at the secondary side of a transformer, and monitoring the secondary current of the current transformer by a voltage detector. CONSTITUTION:A rectifier 3 is connected to the secondary side of a transformer 1, and the output is led from a terminal 9. A current transformer 4 is inserted to the secondary side of the transformer 1. When a resistor is inserted to the secondary side of the transformer 4 to convert a current to a voltage to detect it by a voltage detector 5, it can detect the voltage proportional to the primary current by the operation of a current source at the normal time, but it does not have a function as the current source at the malfunction time. Accordingly, it cannot detect the voltage proportional to the primary current from the resistor. Consequently, the occurrence of a defect can be immediately known by a meter, an alarm lamp or an alarm unit attached to the voltage detector 5.

Title: Method of preventing pulsation in conveyance of pressurized fluid
Inventor: ICHIKAWA MASAYOSHI
IPC: F17D1/20
Filed: 1980-05-14
Abstract: PURPOSE: To efficiently prevent the pulsation of a fluid, by keeping the pressure of air in an internal chamber connected to a passage pipe, higher than the atmospheric pressure.  
     CONSTITUTION: An internal chamber 6, the pressure in which can be increased, is connected to a passage pipe 4 extending from a pressure conveyance pump 43 as a pressure conveying means to a destination 5 in a system wherein a fluid 2 put in a hopper 1 is conveyed under pressure to the destination 5 through the passage pipe 4 by the pressure conveyance pump 3. After the pressure of air in the chamber 6 is heightened, the fluid 2 is conveyed under pressure by the pump 2. After the fluid 2 has passed the part of the passage pipe 4 near the chamber 6, a valve 11 at the chamber is opened to connect the pipe 4 to the chamber 6. As a result, the pulsation of the fluid 2 is absorbed by the pressurized air in the chamber 6. The pulsation is thus suppressed.

Filed: 1990-03-16
Abstract: PURPOSE:To enable easy, high-accuracy measurement by guiding the pulsating flow of a solution which incorporates an electrolyte to nearby one side surface of a charged film which partitions two solutions, detecting the film potential transient response of the charged film in response to the flow, and finding its flow rate from the peak value. CONSTITUTION:A flow rate measuring means consists of an arithmetic unit 13 which converts the detected film potential peak into the flow rate and a film potential detecting means 101, which is equipped with the solutions 3 and 4 which are partitioned with the charged film 2, an intake tube 2 which guides them to nearby the surface of the charged film 2, electrode systems 6 - 12 for measurement, a calomel electrode 1011, a potentiometer 12, etc. When there is no flow because of flow rate variation, the periphery of the surface of the film 2 is filled with a low concentration electrolyte or the other solution which incorporates no electrolyte, but when a pulsating flow is generated, the periphery is filled with liquid incorporating the electrolyte. When the electrolyte concentration is increased, the film potential has a large transient peak temporarily. Consequently, the easy, high-accuracy measurement is available.

Abstract: PURPOSE: To make it possible to readily and reliably measure the area of an object to be plated which has a complicated shape, by submerging said object in an electrolytic solution, and measuring the value of the current flowing then.  
     CONSTITUTION: First, metal test pieces, whose areas are alreadly known and different from each other, are submerged in an electrolytic solution. A given voltage is applied thereto, and the current value at that time is measured in order to obtain the relationship between the current value and the test piece area. Then, to measure the area of an object to be plated, the same electrolytic solution and conditions as used in the current value measurement of the test pieces whose areas were already known are used, and the same voltage is applied to the object to be plated to measure the value of the current flowing at that time. Then, the measured current value is applied to a graph or expression of relation representing the relationship between the previously measured current value and the area. Thereby, the area of the object to be plated is obtained.
